XVaCreateNestedList − allocate a nested variable argument list. 

Synopsis

XVaNestedList XVaCreateNestedList(dummy, ...)

   int dummy;

Arguments

dummyUnused argument (required by ANSI C). 

...Specifies the variable length argument list. 

Availability

Release 5 and later. 

Description

XVaCreateNestedList() creates a nested argument list of type XVaNestedList.  The first argument is an integer value which is unused but required because ANSI-C does not allow variable-length argument lists which do not have any "non-variable" arguments.  This first argument is followed by a NULL-terminated variable-length argument list.  Generally, the arguments will be input method or input context attribute name/value pairs.  Nested lists created in this way may be used in any of the input method and input context functions which require a variable-length argument list.  Also, the XNPreeditAttributes and XNStatusAttributes input context attributes are of this type XVaNestedList.  XVaCreateNestedList() allocates memory and copies its arguments into a single list pointer which may be used as value for arguments requiring a list value.  Any entries are copied as specified.  Data passed by reference is not copied; the caller must ensure that data remains valid for the lifetime of the nested list.  The list should be freed using XFree() when it is no longer needed.
